Abstract:
Saccharmyces cerevisiae 220 has certain resistance to Pb2+ was found through the test of it's cultured on media containing lead cation. Sacchannyces cerevisiae 220 cultured was put into the media cotaining lead cation and it's biosorp-tion to lead cation was studied. The results show this strain has maximum biosorption ratio (96.6%) to 6mg/L lead cation, biosorption-equilibrilium period is 25-30min, biosorption kinitics equation is q-26.318C/ (1 + 0.437C) . Acetic acid is benefit to de-biosorption, glucose and KH2PO4 can improve biosorption ratio to lead cation.
